How it works

Turn a plain-English description of your app into a relational schema and ER diagram in three steps.

  1. Describe your application

    Explain what the app does and what it needs to store — users, orders, projects, whatever the domain requires.

  2. Generate the schema

    The AI designs tables, columns, data types, keys and relationships suited to a production workload.

  3. Read the ER diagram or copy the code

    Switch between the rendered Mermaid ER diagram and the raw schema, then take it into your migration tool.

Frequently Asked Questions

What is DB Designer AI?
DB Designer AI is a free tool that converts a plain-English description of your app into a production-ready relational database schema, rendered as a Mermaid ER diagram with tables, field types, primary keys, foreign keys, and relationships.
Does DB Designer AI normalize the schema?
